甲醛(FA)是一种常见的环境毒素,但也是内源性产生的一系列重要的生物过程,包括线粒体一碳代谢,代谢物氧化,核表观遗传修饰。它的高亲电性使得能够与多种生物亲核试剂反应,这取决于上下文对细胞功能可能是有益的或有害的。新的方法,使检测FA在生命系统中可以帮助解开这个最简单的反应性羰基物种(RCS)的信号/应力二分法,荧光探针FA具有高选择性和灵敏度已经成为有前途的化学工具在这方面。
Formaldehyde (FA) is a common environmental toxin but is also endogenously produced through a diverse array of essential biological processes, including mitochondrial one-carbon metabolism, metabolite oxidation, and nuclear epigenetic modifications. Its high electrophilicity enables reactivity with a wide variety of biological nucleophiles, which can be beneficial or detrimental to cellular function depending on the context. New methods that enable detection of FA in living systems can help disentangle the signal/stress dichotomy of this simplest reactive carbonyl species (RCS), and fluorescent probes for FA with high selectivity and sensitivity have emerged as promising chemical tools in this regard.
